Animal Based Natural Fibres,and Types.
Animal Based Natural Fibres
Introduction
Natural fibers derived from animals have played a crucial role in meeting human textile needs for centuries. These fibers are sourced from the hair, fur, and other specialized structures of various animals, offering unique characteristics that contribute to the diversity of textiles available in the market. The production of animal-based natural fibers involves a combination of traditional practices and modern techniques to harness the raw materials ethically and sustainably.
One of the most widely known and utilized animal-based fibers is wool, sourced primarily from sheep. Wool possesses exceptional insulating properties, moisture-wicking abilities, and a soft texture, making it a popular choice for a wide range of clothing items, including sweaters, scarves, and blankets. Other animals, such as goats (cashmere and mohair) and rabbits (angora), also contribute to the production of luxurious and sought-after fibers.
Silk, another prized natural fiber, is obtained from the cocoons of silkworms. The process of sericulture involves carefully cultivating silkworms and harvesting their silk threads, which are then woven into a fabric known for its smoothness, sheen, and lightweight feel. Silk is often used in the creation of elegant garments, lingerie, and various luxury items.

Properties of Animal-Based Natural Fibers
Animal-based natural fibers, derived from the hair or fur of animals, exhibit various properties that make them valuable for different applications. Here are some common properties associated with these fibers:
1.Softness.
Animal fibers like cashmere, angora, and alpaca are known for their soft and luxurious feel. This makes them comfortable to wear and ideal for producing delicate textiles.
2.Warmth.
Wool, cashmere, mohair, and camel hair are excellent insulators, providing warmth in cold conditions. The natural crimp and loft of these fibers trap air, creating an effective barrier against the cold.
4.Insulating Properties.
Animal fibers, especially wool and alpaca, have natural insulating properties. They can regulate body temperature by trapping air close to the body, providing warmth in cold weather and remaining breathable in warmer conditions.
5.Lightweight.
Despite their warmth, many animal fibers are lightweight. This makes them suitable for creating garments that offer insulation without being overly heavy or bulky.
6.Luster.
Silk, mohair, and certain types of wool (such as merino) have a natural sheen or luster that adds to the visual appeal of textiles. This quality contributes to the luxurious and high-quality appearance of fabrics made from these fibers.
7.Durability.
Animal fibers like llama and horsehair are known for their durability and strength. These fibers can withstand wear and tear, making them suitable for applications where robustness is crucial.
8.Elasticity.
Wool is inherently elastic, allowing it to stretch and then return to its original shape. This property enhances the comfort and fit of garments made from wool fibers.
9.Biodegradability.
Animal fibers are natural and biodegradable, meaning they can decompose over time. This environmental friendliness is a positive aspect compared to some synthetic fibers.
10.Hypoallergenic.
Fibers like alpaca and cashmere are often considered hypoallergenic, making them suitable for individuals with sensitive skin or allergies. These fibers are less likely to cause skin irritation.
Production Process of Animal-Based Natural Fibers
The production process of animal-based natural fibers involves several stages, from the shearing or harvesting of the raw material to the manufacturing of finished products. Here is a general overview of the production process for some common animal fibers:
1.Shearing or Harvesting:
The process begins with the shearing of animals to obtain their natural fibers. Sheep, goats, rabbits, and other animals are sheared or combed to collect wool, cashmere, angora, and other fibers. In the case of silkworms, the pupae are carefully unwound from their cocoons to obtain silk fibers.
3.Sorting and Grading:
After shearing, the collected fibers are sorted and graded based on their quality. This involves separating the coarse outer fibers from the finer, softer fibers and removing impurities such as dirt or vegetation.
4.Cleaning:
The sorted fibers undergo cleaning processes to remove any remaining impurities. This typically involves washing the fibers with water and mild detergents to ensure they are clean and ready for further processing.
5.Carding:
Carding is a mechanical process that aligns and separates the fibers. It helps remove tangles and creates a uniform web of fibers. This step is crucial for ensuring the quality and consistency of the final product.
6.Combing (Optional):
Some fibers, like wool, may undergo an additional combing process to remove shorter fibers and align the longer ones. Combing produces a smoother and finer yarn.
7.Spinning:
The cleaned and carded fibers are spun into yarn through a process called spinning. This involves twisting the fibers together to create a continuous strand of yarn. The thickness and texture of the yarn can be controlled during this stage.
8.Weaving or Knitting:
The yarn is then used in the weaving or knitting process to create fabrics. Weaving involves interlacing yarns on a loom to produce a woven fabric, while knitting involves looping yarn together to create a knitted fabric.
9.Finishing:
After weaving or knitting, the fabric undergoes finishing processes, which may include treatments like washing, steaming, or pressing to improve its texture, appearance, and durability.
